ECR #333753 - TargetMachine is created not only for codegen, but for optimizer as well
	This is to provide target specific optimizations in the intermediate optimizer.
	LLVM 3.6 provides TargetTransformInfo for this purpose which requires TargetMachine.
	No correctness issues will occur if TargetInfo is not created, but optmizations will target generic machine.

	Testing: smoke, precheckin
	Reviewed by Evgeny Mankov
